Developments burning ceramic items indicate a change in the method of combustion, ie from the campfire into a furnace models.<\/span> Furnace models aim to further facilitate the control of fire.<\/span> The hot air will rise, and this became the main principle of the development of the furnace at the time.<\/span> Discovery updraft furnace (fire rises) can be known from several ancient illustrations, especially the days of ancient Egypt.<\/span><\/p>\n This simple combustion furnace starts with the type of furnace kiln bank.<\/span> Along with the production of porcelain materials at 960-1279 in China began to develop the type of bank climbing kiln furnaces are the type of kiln bank terraces \/ terraced.<\/span> Korean people also develop this type of furnace called anagama, which is almost similar to the type of furnace China developed but modified to control the fire.<\/span> In Japan also developed these furnaces in the 17th century by combining the furnace room 20 as high as 6 ft and 8 ft wide.<\/span> After that period, the furnace evolved independently in various civilizations the world to produce a better combustion methods.<\/span> The first ceramic furnace in the form of buildings \/ circular shape \/ tube \/ dome made of local rocks and shards of burnt ceramic bonded to each other with clay mud.<\/span> In some parts made air holes at the same time to pick up belongings burnt.<\/span>
